Description

Technical Field

[0001] The present invention relates to the field of labor protection appliances for power engineering construction, and specifically to a weight-reducing and temperature-reducing high-voltage shielding work clothing equipment. Background Art

[0002] In the prior art, in the field of power engineering construction, high-voltage shielding work clothing is an important labor protection appliance. Due to the need for potential protection, such high-voltage shielding work clothing has a complex structure, a heavy self-weight, uncomfortable wearing, insufficient breathability, and poor temperature adaptability, which directly affects the construction efficiency and operation safety. Summary of the Invention

[0003] The purpose of the present invention is to provide a weight-reducing and temperature-reducing high-voltage shielding work clothing equipment, which can effectively reduce the wearing weight, increase the breathability, reliably shield the high-voltage potential, isolate the environmental high temperature, greatly improve the construction efficiency, and ensure the operation safety.

[0004] Design a weight-reducing and temperature-reducing high-voltage shielding work clothing equipment, which is composed of a mutually connected shielding protection body, a fan pipeline system, and a hovering adjustment system.

[0005] The shielding protection body is provided with a high-voltage shielding work clothing and a mask screen.

[0006] The high-voltage shielding work clothing includes an operator shielding work clothing and a fan pipeline system shielding work clothing. The fan pipeline system shielding work clothing refers to a special fabric that wraps the fan box, cold grid, upper air pipe, middle air pipe, and lower air pipe. This fabric can shield high-voltage arcs and prevent the high-voltage wires from releasing high-voltage arcs to harm the operator when they are working.

[0007] The fan backpack has a semi-open hollow cylindrical fan box inside. The material of the fan backpack can also achieve the effect of shielding high-voltage electricity like the high-voltage shielding work clothing. A cylindrical cage fan is fixed inside the fan box. As Figure 1 .

[0008] The fan backpack is connected to the shielding work clothing through three groups of air pipes, namely the upper air pipe, the middle air pipe, and the lower air pipe. Each group of air pipes is divided into two symmetrically arranged left and right ones, which are respectively led out from the upper, middle, and lower parts of the cold grid opposite to the openings on both sides of the fan box inside the fan backpack and communicated with both sides of the shoulder and neck, both sides of the waist, and the left and right leg parts of the high-voltage shielding work clothing. As Figure 1 .

[0009] The fan is powered by a DC battery, and the DC battery is located between the cold grids on both sides of the fan backpack. As Figure 1 .

[0010] The fan pipeline system is provided with: a fan backpack, a cold grid, an upper air pipe, a middle air pipe and a lower air pipe; the cold grid is provided with a liquid nitrogen bottle, a vaporization chamber, a mask screen, a liquid nitrogen flow pipe and a pressure valve. The air cooled by the liquid nitrogen bottle, the vaporization chamber and the liquid nitrogen flow pipe is blown by the fan and enters the high-voltage shielding suit through the upper air pipe, the middle air pipe and the lower air pipe. A small part of the air escapes through the mask screen, and most of the air flows around the operator's body from left to right and then flows into the fan box from the right cold grid. Then, under the flapping of the cage-shaped cylindrical fan, the air enters the high-voltage shielding suit from the left cold grid again, forming a flow of refrigerated air; the refrigerating nitrogen forms a process of liquid nitrogen vaporization in the liquid nitrogen bottle, the vaporization chamber and the liquid nitrogen flow pipe, and the gaseous liquid nitrogen escapes through the pressure valve, forming a conversion of the refrigerating medium.

[0011] The cold grid is located on both sides of the fan backpack and is composed of a liquid nitrogen flow pipe and a grid page net. The liquid nitrogen flow pipe runs through the center of the entire grid page net in an S shape. There are two pipe orifices at the uppermost end of the liquid nitrogen flow pipe, which are respectively inserted into the liquid nitrogen bottle and the vaporization chamber. The liquid nitrogen bottle and the vaporization chamber are located at the upper part of the fan backpack. Liquid nitrogen is filled in the liquid nitrogen bottle, and the vaporization chamber is hollow and a pressure valve is installed at the top end. The top of the vaporization chamber is slightly higher than the top of the liquid nitrogen bottle. As Figure 1 、 Figure 2 。

[0012] The hovering adjustment system is provided with a six-rotor unmanned aerial vehicle (UAV), a UAV bracket and a flight attitude sensor. The flight attitude sensor can detect the flight attitude of the six-rotor UAV and feedback it to the flight control system of the UAV, enabling the UAV to move forward in time or stop moving forward in time, so as to avoid the flight attitude tilt caused by the pulling of the shielding protection body when the UAV lags behind or is ahead of the operator.

[0013] The UAV is a six-rotor UAV. Two brackets of the UAV are respectively hung on the top of the cap of the shielding suit and the top of the fan backpack through nylon ropes in a front-back manner. Along the flight direction of the UAV, there is a flight attitude sensor on the top of the UAV. The flight attitude sensor is a thin tube filled with mercury. The volume of the mercury is 1 / 5 of the volume of the thin tube, and there is a contact switch at each of the front and rear ends of the thin tube. As Figure 1 、 Figure 3 。

[0014] The beneficial technical effects of the present invention are as follows: Since the temperature control circulation mechanism is provided with a fan backpack, a cold grid, an upper air pipe, a middle air pipe and a lower air pipe; and a liquid nitrogen bottle, a vaporization chamber, a mask screen, a liquid nitrogen flow pipe and a pressure valve are arranged in the cold grid, the air cooled by the liquid nitrogen bottle, the vaporization chamber and the liquid nitrogen flow pipe enters the high-voltage shielding suit through the upper air pipe, the middle air pipe and the lower air pipe, and escapes through the mask screen, forming a refrigerated air circulation, thereby reducing the ambient temperature of the wearer. At the same time, since the unmanned aerial vehicle and the control mechanism are provided with a six-rotor unmanned aerial vehicle, an unmanned aerial vehicle bracket and a flight attitude sensor, the flight attitude sensor can sense the flight attitude of the six-rotor unmanned aerial vehicle and feedback it to the flight control system to automatically pause or start the forward flight of the unmanned aerial vehicle, achieving the reduction of the weight of the high-voltage shielding suit while automatically following the wearer forward. The present invention also has the advantages of reasonable structure, good cold air fluidity, high cooling efficiency and good safety. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The present invention will be described in detail below according to the embodiments provided in the drawings in two parts.

[0018] The first part is the structural composition.

[0019] The shielding protection body 20 includes a high-voltage shielding suit 1 and a mask screen 8; The fan pipeline system 21 includes a fan backpack 2, a fan box 3, a cage fan 4, a cold grid 5, a liquid nitrogen bottle 6, a vaporization chamber 7, a mask screen 8, an upper air pipe 9, a middle air pipe 10, a lower air pipe 11, a fan battery 15, a liquid nitrogen flow pipe 16, mercury 17, a contact switch 18, and a pressure valve 19; The hover adjustment system 22 includes a six-rotor unmanned aerial vehicle 12, an unmanned aerial vehicle bracket 13, and a flight attitude sensor 14.

[0020] The second part is the operation process.

[0021] After the fan backpack 2 and the high-voltage shielding suit 1 are hung by the six-rotor unmanned aerial vehicle 12 and move forward with the operator, the wearing load of the operator is reduced. The fan in the fan backpack 2 blows the air in the high-voltage shielding suit 1 and the fan box 3 to rotate clockwise from left to right through the upper air pipe 9, the middle air pipe 10, and the lower air pipe 11 in a circular motion. The low-temperature liquid nitrogen flowing into the liquid nitrogen flow pipe from the liquid nitrogen bottle 6 cools the grating pages of the entire cold grating 5. When the air passes through the cold grating 5, the air becomes cold air. The cold air enters the high-voltage shielding suit 1 through the upper air pipe 9, the middle air pipe 10, and the lower air pipe 11, circulates clockwise around the head and shoulders, chest and abdomen, and legs and waist, and blows through, and part of it escapes from the mask screen 8 on the face of the high-voltage shielding suit 1.

[0022] The liquid nitrogen bottle 6 is slightly lower than the vaporization chamber in terms of the horizontal height. The liquid nitrogen in the liquid nitrogen bottle 6 flows down along the liquid nitrogen flow pipe and then flows back up along the liquid nitrogen flow pipe to the bottom of the vaporization chamber 7 due to the water pressure. Here, since no more liquid nitrogen rushes in and the lower temperature cannot be maintained, the liquid nitrogen vaporizes from liquid to gas in the vaporization chamber 7. After the air pressure accumulates to a certain extent, the gaseous liquid nitrogen escapes from the pressure valve 19.

[0023] The mercury in the thin tube of the flight attitude sensor 14 will flow to both ends of the thin tube when the flight attitude tilts forward and backward. When the six-rotor unmanned aerial vehicle 12 moves forward with the operator walking forward and drives the six-rotor unmanned aerial vehicle 12 above to move forward, the six-rotor unmanned aerial vehicle 12 is briefly in a backward-tilted flight attitude; when the six-rotor unmanned aerial vehicle 12 moves faster than the operator and exceeds the operator, the six-rotor unmanned aerial vehicle 12 is in a forward-tilted flight attitude. In both tilted flight attitudes, the mercury 17 in the thin tube will fill the gap between the two contacts of the front or rear contact switch, making the front or rear contact switch 18 turn on. After the front contact switch 18 turns on, it is judged that the flight attitude is forward-tilted, and it is judged that the six-rotor unmanned aerial vehicle 12 is ahead of the operator at this time. At this time, the control system automatically pauses the forward flight of the six-rotor unmanned aerial vehicle 12; after the rear contact switch 18 turns on, it is judged that the flight attitude is backward-tilted, and it is judged that the six-rotor unmanned aerial vehicle 12 lags behind the operator at this time. At this time, the control system controls the six-rotor unmanned aerial vehicle 12 to fly forward slowly. By triggering the opening and closing of the contact switch 18 through the feedback of the flight attitude sensor 14 to control the forward flight or suspension of the forward flight of the six-rotor unmanned aerial vehicle 12, it is possible to well control the six-rotor unmanned aerial vehicle 12 to always hover directly above the operator in a relatively horizontal flight attitude, and the fan backpack 2 and the high-voltage shielding suit 1 are hung above the operator's head and move forward in a straight line synchronously with the operator. Since the high-voltage wires are usually laid flat in a straight line, this method can be applied to high-voltage operations while wearing the high-voltage shielding suit 1.
